This invention relates to machines for forming conical wound. packages. In one type of these machines a conical element for receiving the windings,orrather a paper or equivalent hollow core for-the windings, is rotated around an axis passing longitudi nally therethrough in parallelism with the taper of the cone (as by. said element being a sleeverevoluble around a conical stub over which itis fitted and which is set so that its taper and said axisare parallel), and the yarnguide in receding from the package does so in a path perpendicular to'such an axis instead of one perpendicular to thetrue axis of the cone. The consequence of such a construction is that theends of the package do not conform to planes (perpendicular to the true axis of the package cone)but the smaller end is dished or concave and the largeror buttend convex, which of course reducesthe stability of. the wound mass Myinvention contemplates novel means for forming aconical woundlpackage so that the-ends thereof may conform to plane-s perpendicularto the true axis ofthe package cone, and also so that any desired degree of taper may be attained.

It further contemplates'a ,novel detector generally useful fordetecting slubs and the a like in yarn or thread.

Figs. 6 and 7 w are sections onlines -6 -6 and 7 -7 of Figsji 5, respectively; Figs. :8 and!) show a detail of the yarn traversing means and Fig. '10.shows the slub detector in plan.

In the frame lIishorizontallyjournaled a drive-shaft 2 dr'iving,f.through gearing 3, a horizontal shaft, 4 -wl 1ich, through-a clutch :5, drive-sthelspindle 6, alined therewlth and v V projecting fromthe frame, and also, through belt-and-pulley system 7, a shaft 8 which,

througha pinion thereon (not shown) and meshing" with agear 9, drivesa barrel cam 10 whose axis of rotation is horizontal and which causes traverse of the yarn lengthwise ofthe package being formed. A clutch le- .Ver 11 isnormally influenced by a spring. 12 to hold the clutch 5 open, with the spindle stopped, but i-sshifted by hand, to start the spindle, until it is dogged by lever 13. This lever is adapted to be automatically tripped by the rise of a push-rod 14- efi'ected, when the yarn breaks, by a lever 15 normally held against falling by the yarn, which it engages at 15, between the supply package A and-a guide at16. .So much is in general Well known. The :lever 13 is also adapted to'be automatically tripped by movement of lever .l 5 eflected from the. movable element of a slubedetector, ,as .will hereinafter appear.

A'movable (here fulcrumed) structure to traversingmeans, receiving its motion from cam 10, ispirovided as follows: 17 is a yoke fulcrumed onthe shaft of said cam so that (since said shaft and the spindle axis are parallel) it is niov'able perpendicularly to the latter; in the present case-its movement from the spindle during a winding operation s obtained from the growingpackage toward which it. is normally urged by a weight 17f,

ly through a slot (Fig. 2) in the front plate of frame l, forward ofwhich itmay have an additional leg- 17? with a bearing'on said affordsupport and. a guide lfor'the yarnshaft at 17, and it has an ar'm or' extension 18 pivotally, adjustable. therein so asto be set in parallelism with the taper ofthequill,

port affording reciprocated by the cam 10, and a link 23 pivotally connecting the traverser and traveller. The details of theseparts in their preferred form will be later described.

It willappear' from the foregoing that when the winding unit is in operation, the tapered core rotating and the yarn-traversing means reciprocating, and the latter movlng away from thepackage being formed asthe u latter grows in diameter, the ends of the package will be formed in planes perpendicu lar to the true axis of the package (see F1g. This is because, through those (reciprocating) movements of the travers'er bywhich it imparting reciprocation to the traverser reciprocation which is offset relatively to the package lengthwise of its axis and said parts of the support must be correspondingly offsetwith respect to each other, a traveller, as 22, is arranged by said means and to this the traverser is pivotally connected, as by llIlk 23, to permit the said adjustment thereof.

' The traverser is an inverted T-shaped plate having a yarn guide 21 at the top and its lower edge sliding in a groove 18 in arm 18, against whose fiat face 18 the plate bears;

it may have a bent-off extension 21* engaged in another groove 18 to prevent lts rlsing and being unshipped from the arm, and another such extension 21 aifording'apivot for the link 23. The traveller 22-may also be a plate sliding in a slot 1'7 of vtravels in the groove of the cam 10 the plate, opposite extensions 22 'spectively engaged 111 a groove 17" and afcross-bar 17 and having, below thelatter', a bent'off extension 22 carrying a roller 22 which and, above and 22 re- L'fording a pivot for the link.

i As for automatic stopping on presence of i a slub: A toggle lever 24, controlled by a ,1 ment actuate lever spring 25, isfulcrumed on a bracket 26 and adapted to be moved by the slub, togglewise,

thereof and on such moveagainst a'stop 26 15,through a hnk 27. A

, novel slub detector is mounted on'and formed in part by j p j v 28 and 29 are plates secured to the lever above and below (so that they are thus spaced by)- the free e'nd of this lever, thus:

the latter, having yarn-receiving or. detecting slots 28 and 29 at right angles to each other and entering from' edges of the plates and each open later lly of itself to the space beonpart 17 of said support for tween the plates. This arrangement of the plates, taken with the relative arrangement of the slots, makes it possible for the operator unerringly and quickly to thread the de tectorby rotative movement of the yarn first in one and thenin the other direction, the yarn entering the space between the plates between the. two movements.
